This is my 4th year with one of these and I can honestly say that life would be chaos without it. It is the only planner I've found with 6 columns, so great for families with 4 children. Also, the acetate overlay is a fantastic idea - you put all of your regular activities on it and it just transfers from one week to the next. Nice size boxes for each person each day, and useful list space down the side. It's fab!
